Homeschool Math (aka baking muffins)

After my earlier post with the muffin recipe, Berrik and I set off to make the muffins.  It turned into a major math lesson, with Berrik none the wiser about doing school work!  Here’s some of what we did:

Preheating the oven.  In Math this morning Berrik was learning about number placement on ‘decimal’ street, including 100s, 10s, and 1s.  We used that learning to preheat the oven to 350F.  Simple stuff, but nice reinforcement of what we were doing earlier.

Preparing the pan.  I asked Berrik to estimate how much coconut oil he would need in order to grease all 12 muffin holes, and then had him spoon the amount he though he would need into the little glass bowl.  When he was done greasing the pan, he realized he had overestimated the amount and said he would use less next time.  We talked about whether he thought he had used 1/2 the amount of coconut oil, or less than that.

Measuring the ingredients.  The bananas allowed for a review of simple addition and subtraction.  We did both, which I think is so good to promote understanding that addition is just the opposite of subtraction.  This was easy for him, but always a good review.  After I quizzed him on a couple, he was then supplying the equations and answering them himself.

The rest of the ingredients.  Talking about the difference between 1/2 cup and 1 cup and physically being able to see that 1 cup is double the amount of 1/2 cup is a great way to promote understanding of fractions.  Measured with teaspoons as well, and then estimated the right amount of cinnamon.  More addition and subtraction with the eggs, but generally decided that learning how to crack the egg was more important than the math.  Egg cracking is a life skill.  Everyone should know how to crack an egg.  🙂

Chocolate chips:  Berrik identified the pattern he wanted to use and wrote it on a sheet of paper to help him remember it.  Then he followed through and created the pattern 3 times.  I had him figure out how many times the pattern would repeat before he started, and while it took him a little bit to figure it out, he was able to get the answer.   When he finished he confirmed that his pattern repeat guess was correct (and sounded pretty surprised that it was correct, which was funny).  He also informed me that he would eat the 5 and 4 chocolate chip muffins and McKenna and Avi were welcome to the 3 & 2 chocolate chip muffins.  Definitely my kid!img_6775

We put the muffins in the oven and set the timer.  I made him read to figure out which button said ‘kitchen timer’ and then punch in the amount of time.  His concept of time isn’t great, but he thought that 25 minutes seemed like a perfect amount of time to play outside to ‘get a good appetite for eating muffins’.  I’d love to spend some time inside his brain.  It’s so funny and busy in there.

And finally once the muffins were baked, we discussed more math using word problems. If Berrik ate 2 and mom ate 1, how many would be left for McKenna and Avi?  What if McKenna and Avi each had 1, how many would be left when Dad gets home for dinner?  If Berrik ate all the 4 & 5 chocolate chip muffins, how many would he have eaten?  I had to repeat these a few times (processing word problems is a real challenge for Berrik), but we used the muffins as manipulatives and he was able to figure out the answers.
